DETAILED DESCRIPTION OF PREFERRED EMBODIMENT

FIG. 1 is a top view of a first embodiment of the present invention.FIG. 2 is a perspective view in partial section of the present inventionin FIG. 1. FIG. 3 is an enlarged cross sectional side view of thepresent invention in FIG. 1 showing that the present invention enclosesthe toilet seat 90. FIG. 4 is a top view of the present invention inFIG. 3 showing that the present invention encloses the toilet seat 90.With reference to FIGS. 1 to 4, a first embodiment of a slip-in typesanitary cover for toilet seats in accordance with the present inventionis a plastic bag that is made of polymer material, such as polyethylene.The slip-in type sanitary cover comprises two opposite sides, a bagopening 10, two side edges 20, a closed side, a bag space 40 and anexcreting hole 50.

The bag opening 10 is formed at a side of the slip-in type sanitarycover. The side edges 20 are respectively located at the opposite sidesof the slip-in type sanitary cover. The closed side of the slip-in typesanitary cover is opposite to the bag opening 10. Preferably, the closedside of the slip-in type sanitary cover is a straight sealing strip 30.

The bag space 40 is formed in the slip-in type sanitary cover forholding a toilet seat 90 inside and is formed between the bag opening10, the side edges 20 and the closed side of the slip-in type sanitarycover.

The excreting hole 50 is formed through a central section of the slip-intype sanitary cover, communicates with the bag space 40 and has twoopenings 51 respectively located two opposite sides of the excretinghole 50.

Preferably, the first embodiment of the slip-in type sanitary coverfurther has two sealing units 60 respectively connected with the sideedges 20. The two opposite ends of each sealing unit 60 are respectivelyconnected with a corresponding one of the side edges 20 of the slip-intype sanitary cover and a central segment of the sealing strip 30. Eachsealing unit 60 is a linear strip to form a shape of the bag space 40 asa convex hexagon.

With reference to FIGS. 1 and 4, the slip-in type sanitary cover isabout to enclose the toilet seat 90. Two top sections 70 of the slip-intype sanitary cover adjacent to the bag opening 10 are grabbed and theslip-in type sanitary cover is pulled to enclose the toilet seat 90completely via the bag opening 10. The slip-in type sanitary cover ispulled until the sealing strip 30 abuts the front edge 923 of the toiletseat 90.

The sum of numbers of the side edges 20, the sealing units 60 and thesealing strip 30 is five and the side edges 20, the sealing units 60 andthe sealing strip 30 are respectively tangent to the outer rim 92 of thetoilet seat 90. When a user sits on the slip-in type sanitary cover inaccordance with the present invention, the slip-in type sanitary coveris tightened by the weight of the user. Accordingly, the side edges 20,the sealing units 60 and the sealing strip 30 can respectively andtightly abut the left edge 921, the left-front edge 922, the front edge923, the right-front edge 924 and the right edge 925 of the outer rim 92of the toilet seat 90. Consequently, the slip-in type sanitary cover canbe securely positioned on the toilet seat 90.

The excreting hole 50 corresponds to and aligns the seat hole 91.Therefore, the user can excrete via the excreting hole 50. After theexcretion, two bottom sections 80 of the slip-in type sanitary coveradjacent to the sealing strip 30 are grabbed. The slip-in type sanitarycover is pulled to fall off from the toilet seat 90 and can be thrownaway.

With reference to FIG. 5, a second embodiment of the slip-in typesanitary cover for toilet seats in accordance with the present inventionis substantially the same as the first embodiment.

The closed side of the slip-in type sanitary cover is a straight sealingstrip 30A.

The slip-in type sanitary cover has two sealing units 60A respectivelyconnected with the side edges 20A.

Each sealing unit 60A comprises three continuous linear strips 61A tomake a shape of the bag space 40 become a convex decagon.

The sum of numbers of the side edges 20A, the linear strips 61A and thesealing strip 30A is nine and the side edges 20A, the linear strips 61Aand the sealing strip 30A are also respectively tangent to the outer rim92 of the toilet seat 90. Because the sum of numbers of the side edges20A, the linear strips 61A and the sealing strip 30A of the secondembodiment is larger than that of the side edges 20, the sealing units60 and the sealing strip 30 of the first embodiment, the load applied toeach side of the second embodiment of the slip-in type sanitary coverdue to the weight of the user is smaller than that applied to each sideof the first embodiment. The structural strength of the secondembodiment is enhanced. Accordingly, the second embodiment can be madeof a material thinner than that for the first embodiment for achievingthe same structural strength.

With reference to FIG. 6, a third embodiment of the slip-in typesanitary cover for toilet seats in accordance with the present inventionis substantially the same as the first embodiment.

The closed side of the slip-in type sanitary cover is a straight sealingstrip 30B. The slip-in type sanitary cover has a sealing unit 60B. Theseal unit 60B is a half ellipse being tangent to the sealing strip 30Band has two ends respectively connected with the side edges 20B of theslip-in type sanitary cover.

The side edges 20B and the sealing unit 60B are shaped like as anellipse and can conform to the shape of the toilet seat 90. Therefore,the sealing unit 60B can be regarded as a group comprising infinitetangent lines which are tangent to the outer rim 92 of the toilet seat90.

With reference to FIG. 7, a fourth embodiment of the slip-in typesanitary cover for toilet seats in accordance with the present inventionis substantially the same as the first embodiment.

The closed side of the slip-in type sanitary cover is a straight sealingstrip 30C. The slip-in type sanitary cover has a sealing unit 60C. Thesealing unit 60C has dots which are tangent to the outer rim 92 of thetoilet seat 90 by any format, such as multiple dotted lines 61C arrangedin radius. Each dotted line 61C has a distal end. A curve passingthrough the distal ends of the sealing units 60C is half-elliptic. Theside edges 20C and the sealing strip 30C are tangent to the outer rim 92of the toilet seat 90.

The sealing unit 60,60A,60B,60C could be any format as long as thesealing unit 60,60A,60B,60C is tangent to the outer rim 92 of the toiletseat 90, the present invention does not limit the shape, width or numberof the sealing unit 60,60A,60B,60C.

With reference to FIG. 8, a fifth embodiment of the slip-in typesanitary cover for toilet seats in accordance with the present inventionis substantially the same as the first embodiment. The fifth embodimentdoes not have the sealing unit 60,60A,60B,60C. The closed side of theslip-in type sanitary cover is a straight sealing strip 30D. The sum ofnumbers of the side edges 20D and the sealing strip 30D is three. Theside edges 20D and the sealing strip 30D are tangent to the outer rim 92of the toilet seat 90. Because the sum of numbers of the side edges 20Dand the sealing strip 30D of the fifth embodiment is smaller than thesum of numbers of the side edges 20, the sealing units 60 and thesealing strip 30 of the first embodiment, the fifth embodiment isthicker than the first embodiment to achieve the same structuralstrength.

In conclusion, the present invention is to resolve the problems that theconventional sanitary cover easily slides and is difficultly positioned.The present invention tends to provide the slip-in type sanitary coverhaving an essential characteristic that the slip-in type sanitary coveris bag-shaped. The slip-in type sanitary cover can directly enclose thetoilet seat 90 and be stretched tight by a pressure of a user's sitting.Each side of the slip-in type sanitary cover tightly abuts the toiletseat 90 for positioning because of a tension phenomenon caused by theuser's sitting. The present invention does not belong to the prior art,such as an improved toilet seat or the conventional sanitary coversadhering to or hooking the toilet seat 90.
